MANIFOLDING MACHINE.

Application filed February 18, 1924. Serial- No. 693,483.

Our invention relates to roll rewind mechanism for manifolding machines particularly such machines as have full sized record webs.

It is our object to provide for an improved rewind mechanlsm for a full sized record web in manifolding machines. In this connection we desire to provide for a rewind to form a tight and compact roll of a retained paper web, after it has been fed along with the other webs that are to be issued. One of the particular improvements in our record rewind comprises the addition to the friction feed of the rewind, of a short positive feeding impulse to get the rewind roll started, and thus to take up slack.

We accomplish the objects above stated, and other points to be noted, by that certain construction and arrangement of parts to be hereinafter more specifically pointed out and claimed.

In the drawings:

Figure 1 is a detail side elevation of the main feed devices and the rewind mechanism and stops.

Figure 2 is an elevation of the initial starting pawl of the rewind.

Figure 3 is an elevation of the arm for said pawl.

Figure 4 is a detail assembly in side elevation of the said arm, the pawl, and the ratchet on the rewind device.

Figure 5 is a detail planview of the rewind devices.

For a description of the framework parts and general operation of the manifolding mechanism, we refer to United States Patent No. 1,439,135, dated December 19, 1922.

We show a main feed shaft 5, mounted in 40 the side frames, which is to be revolved, a

complete rotation for each feeding operation of the machine as by an operating handle (not shown). We show a writing table 7 over which the Webs of paper are fed by the feeding device and which is used as a support when writing is made on the topmost web, which writing is transferred by carbon paper or other means to the webs bencnh.

The paper feed pin wheels of usual type, as indicated at 40, are mounted on the main feed shaft 5, and engage the paper webs as they pass over the writing table. The record web passes from the pin wheels down 66 and over a rewind roll 41.

The rewind roll pinion 42 is fast to a friction wheel 43, which is engaged by a friction wheel 44, on the rocking frame 45. This frame 45 is mounted on the stud 46 in the side wall which stud carries a gear 47 meshing with the gear 48 which is secured to the friction wheel 44, so that this gear 48 moves in a planetary manner around the gear 47 The gear 47 is driven from a gear 49 on the main feed shaft alongside of one of the pin wheels, and the frame is rocked by means of a spring 50 so as to maintain the friction between the two friction wheels. In order to increase the friction at the in: ception of frictional grip, a lever 51 is mounted within the machine connected by the spring 52 to the rocking frame, and this lever is pressed down during each feeding operation, and preferably at the inception thereof, by means of a stud or roller 53 on the gear 49. v

This lever extends forward beyond the gear 49 wherein it is equipped with a pawl 54 held by a spring 55, and the lever is guided by a screw projecting through a slot 56 in the lever. At the time that the lever is depressed bythe roller, the pawl 54 will engage gear 42 and force the rewind friction wheel and rewind roll forward through the short part of a revolution. This construction gives a positive advance to the record sheet, and takes up with a snap the accumulation of paper between the rewind roll and the pin wheel feed, which accumulation takes place becausethe rewind is stopped at another point before the end of each pin wheel feeding cycle.

This stop is provided by means of a slider 60, mounted by means of a slot and screw structure 61, so that it lies alongside of the gear 49, and will be thrust over by the roller thereon. This slider has an abutment with the top of a stop lever 62, pivoted at 63, and having a pawl 64 thereon. The pawl, when the lever is rocked by thrusting on the slider, will mesh with the gear 42 on the rewind and stop its motion, forcing the friction to slip. The spring 65 pulling on the lever also applies force to the slider so that it follows the feed shaft, and is ready for another operation by the roller, at each cycle of feeding movement of the pin wheels.

Thus in operation, the stud or roller on the gear 49, i. e. on the main feed shaft, is so located, by preference that as the feed com- 1 mences the inhibition of the rewind is re-' leased, and thereupon the starting pawl comes into contact withthe gear 42 on the friction wheel of the rewind and gives it an initial impulse. At the same time the added friction of the extended spring of the rocking lever gives an initial binding frictional contact of the rewind feed proper, and together these devices act to insure the feeding action which gives a tightly wound roll, taking up the slack developed by stopping the rewind feed before the pin wheel feed is stopped.

Where the roll is large, the effect on the rewind, of the positive starting impulse from the pawl and lever, is to take up on the core of the roll making it tighter.

Also, when the rewind roll is large and heavy, we have found that merely tightening up the friction does not effectively start up the rewind, if the machine is carelessly operated. When the rewind rollis small, the starting pawl will not come into play unless the friction feed for some reason does not operate properly. a

The timing of the operation of the several elements of the fewind control is not essential, and the invention herein is not to be limited to the exact periods of operation last above defined.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent, is:-

1. In combination with a paper feed in a manifolding machine, a rewind roll, a friction drive for said rewind roll, driven from the paper feed, and means driven from the paper feed imparting a positive feeding starting motion to the rewind roll in addition of the friction drive.
